Compliance

Welcome to your trusted local CPA in Grants Pass. At John A. Warekois, CPA, we provide a full suite of financial services designed to help local business owners and individuals succeed—with deep expertise in CFO strategy, business tax, payroll, bookkeeping, financial advising, HR, IRS resolution, and personal tax preparation.

Whether you’re a growing company or a person with complex tax needs, you’ll receive personalized service rooted in decades of experience and local insight.

CFO Services

Offer high-level financial leadership without the cost of a full-time CFO. We partner with Grants Pass area businesses to guide growth, budget forecasting, cash flow optimization, and strategic decision-making.

You’ll get clear insights on profitability, capital needs, financial controls, and planning. As your virtual CFO, we act as your financial compass—especially useful when you’re scaling, pivoting, or managing transitions.

Business Tax Preparartion

Navigating business tax rules in Oregon (and federal tax law) can be complex. We work year-round to maintain compliance, reduce liabilities, plan ahead for tax-advantaged decisions, and respond quickly to changes in law.

Whether you’re organized as a corporation, S-corp, LLC, or partnership, we tailor strategies to your entity and industry. For Grants Pass businesses, we also stay current on Oregon-specific rules and local incentives to help you keep more of your earnings.

Bookkeeping Support

Accurate bookkeeping is the foundation of financial clarity. We handle day-to-day accounting—tracking income, expenses, reconciling accounts, and generating monthly reports—so you always know where your business stands.

Clean records help you make sound decisions, simplify tax time, and monitor your performance. We’ll free up your time so you can focus on your business, not spreadsheets.

Financial Advising

Your financial data holds insight—our job is to help you act on it. As your advisor, we analyze your operations, identify opportunities, manage risk, and coach you on investments, financing, cash-flow decisions, and long-term planning.

Whether you’re preparing for a business expansion or want better clarity in your financial path, we’ll help you build a roadmap toward sustainable success.

Payroll Services

Payroll shouldn’t be a headache. We take care of payroll processing, tax withholding, filings, and compliance—so your employees are paid timely and accurately, and you avoid penalties.

We serve businesses in Grants Pass and surrounding areas of all sizes. As your business grows, our payroll solutions scale with you, supporting direct deposit, labor tracking, benefits, and quarterly/year-end filings.

Human Resource Services

Especially for businesses in Grants Pass and Jackson County, we help you stay compliant with local labor laws, maintain equitable policies, and build a strong workplace culture.

I highly recommend people needing tax preparation and catch-up on their back taxes to Jake over at John Warekois. Over there, CPA also stands for Confidence, Professionalism and Accountability. I’ve gotten to know Jake very well recently and am confident the team he works with in the office will be able to navigate your personal or business tax situation as well as being able to help you with your business start-up, bookkeeping, payroll and more as you grow.

John and staff are knowledgeable and caring CPAs who can help individuals and small businesses in Oregon, California and other states with tax preparation and tax planning services. John's "CFO for hire" services can also help small businesses with business planning, tax planning and audit services. It's a great way for startups or businesses too small to have their own CFO get the expertise and experience they might not be able to hire otherwise.
